METHOD OF JOINING PIPES WITH INNER ANTICORROSIVE COATING

摘要

FIELD: pipeline transport.;SUBSTANCE: method comprises fusing corrosion-resisting metal on the zone of the inner surface directly adjacent to the faces of pipes, lining the inner surface of the pipe ends including the surface of the fusing by adhesion coating made of heat-resistant corrosion-resisting material, applying anticorrosion coating on the inner surface of pipes including the surface of lining, and joining pipes by welding. The adhesive coating made of the heat-resistant corrosion-resistant material is made by gas-thermal spraying of the corrosion-resistive metal.;EFFECT: enhanced reliability.;1 cl, 2 dwg
